Piloted valve problem
Is there anyone here who has some experience with sub-base mounted
pneumatic valves? The valve that controls the speed adjustment motor is not working quite right. I know the follownig. 1. It is a sub-base mounted valve with 5 ports. 2. It has two soleniods. 3. When air is applied directly to the speed control motor, without the valve, the motor works great. 4. When I use the soleniod valve to control the motor, it hisses a lot and i barely moving the motor (compared to previous test). 5. I took the valve apart and did not find anything obviously wrong: http://igor.chudov.com/tmp/SpeedValve/ I have a feeling that I simply did not find what was wrong with the valve. My first question is, does it look like a standard sub-base valve? What are the standards? Can it be replaced with something off the shelf? My second question, is how would I go about diagnosing why exactly does this not seem to work right. i |

Haven't seen it as I am on dial-up and your pictures are usually quite large. But have you considered using any 4-way valve? Just have to plumb it in and wire it up. My second question, is how would I go about diagnosing why exactly does this not seem to work right. i -- Dan H. northshore MA. |

Yep, if I fail at this one, I will just get another valve. My second question, is how would I go about diagnosing why exactly does this not seem to work right. i |

I didnt think of this, because most machine shops now days use either screw compressors and dryers, or dryers alone..and you dont have a dryer, do you? Pick one up at an auction.

On sale and with coupon I believe it cost me $250. I got one for the air at the plant. Had it for 2+ years. Beware, the automatic water dump has never worked on ours and we clear it manually every morning. Except for that, works well. Froze up a few times when we didn't clear the tank soon enough. Be sure to plumb it with air bypass capability and pipe unions for easy removal and repair. Paul |
